Automatic Charging of Multiple Smartphones Using Light Beam

Abstract

The fastening of the communication is due to the blessing of electronic gadgets like smartphones and evolving data connectivity. The challenge that is faced is the energy drain of these gadgets that makes it mandatory to charge them multiple times a day. Any system that is capable of performing this task without the user’s knowledge and effort would really be a boon to the society. The proposed work aims at charging the gadgets using light beam. A new approach called auto-charge is used. The Auto-charge approach is based on two steps. First, we leverage solar charging technique but use it in indoor spaces, to remotely charge a smartphone using a light beam without a wire. Second, we employ an image processing based technique to detect and track smartphones on a desk for automatic smartphone charging. The auto-charge consists of a controller, rotator, light and camera. The prototype is able to detect the presence of smartphone within seconds and charge it as fast as existing wired chargers. Auto-charge is able to largely reduce the user’s efforts in smartphone charging and keeps the process absolutely user unaware.
